Pencil sharpener having a guide element for discharging shavings

Abstract

A pencil sharpener (1) having a sharpener body (2), having at least one guide cone (7) situated in the sharpener body (2) for guiding the pencil tip (5) during sharpening, and having a cutting blade (3) fixed to the sharpener body (2), tangentially with respect to the guide cone (7), for shaving the pencil tip (5) in such a way that the pencil tip (5) at the front end has a tapered pencil lead section (24) without casing material, and an adjoining casing section (26) in the center longitudinal direction (20) of the pencil (4) with a pencil lead casing (23) made of casing material, in which the pencil lead (25) of the pencil (4) is embedded, with a guide element (16), which is situated in the area of the main cutting edge (12) of the cutting blade (3) and which engages with the pencil tip (5) in the area of the separating line (27) in the transition area between the pencil lead section (24) and the casing section (26), and which acts on the pencil tip (5), without cutting, in such a way that the shavings of the pencil lead material in the pencil lead section (24) and the shavings of the casing material in the casing section (26) are discharged separately.

1 . A pencil sharpener comprising:
 a sharpener body;   at least one guide cone situated in the sharpener body for guiding a pencil tip during sharpening;   a cutting blade fixed to the sharpener body, tangentially with respect to the at least one guide cone, for shaving the pencil tip in such a way that the pencil tip at a front end has a tapered pencil lead section without casing material, and an adjoining casing section in a center longitudinal direction of the pencil with a pencil lead casing made of casing material in which the pencil lead of the pencil is embedded; and   a guide element, which is situated in an area of a main cutting edge of a cutting blade and which engages with the pencil tip in the area of the separating line in the transition area between the pencil lead section and the casing section, acts on the pencil tip, without cutting, in such a way that shavings of the pencil lead material in the pencil lead section and shavings of the casing material in the casing section are discharged separately.   
     
     
         2 . The pencil sharpener of  claim 1 , wherein the guide element is supported on the cutting blade and is longitudinally displaceable in the longitudinal direction of the main cutting edge of the cutting blade and/or rotatable. 
     
     
         3 . The pencil sharpener of  claim 1 , wherein a guide rib is the guide element and bridges a shavings discharge joint. 
     
     
         4 . The pencil sharpener of  claim 1 , wherein the guide element is fixed to a body edge opposite from the main cutting edge and an adjoining area of the sharpener body, and the guide element protrudes in the direction of the main cutting edge in such a way that the guide element at least partially bridges a shavings discharge joint formed between the main cutting edge and a body edge. 
     
     
         5 . The pencil sharpener of  claim 4 , wherein the guide element is detachably fixed to the sharpener body. 
     
     
         6 . The pencil sharpener of  claim 1 , wherein the guide element is fixed to a functional part that is detachably fixed to the sharpener body. 
     
     
         7 . The pencil sharpener of  claim 6 , further comprising a cleaning rod as a functional part. 
     
     
         8 . The pencil sharpener of  claim 6 , further comprising a shaping tool as a functional part. 
     
     
         9 . The pencil sharpener of  claim 1 , wherein a guide protrusion, as a guide element, situated in an area of a shavings discharge joint between the main cutting edge of the cutting blade and the body edge of the sharpener body oppositely situated in a cone transverse direction. 
     
     
         10 . The pencil sharpener of  claim 9 , wherein the guide protrusion is situated at a joint of a shavings collection container that is divided into two parts by the joint.
